Field of Research: Animal sperm preservation and evaluation of sperm quality

Research summary:

As half of almost every life in mammals is generated from a spermatozoon, it is interesting to conduct research on this cell. “Sperm cryopreservation”, one of the interesting topics, means long-term storage of male gametes at sub-zero temperatures. Many factors influence the quality of post-thaw spermatozoa and therefore the success of sperm cryopreservation such as freezing media, cryoprotectants, freezing and storage temperatures as well as storage time. These factors have been studied and/or reported, as original research, brief communication and review article, by Dr. Kakanang Buranaamnuay.
